cpu temp CPU temperature really high

[Norine]

Hi all,

 

I just finished assembling my new PC, and I've noticed that the CPU temperature has been really high since the beginning. I have a Ryzen7 2700x CPU and Corsair H100i v2 cooler. The I've attached a screenshot of Corsair Link monitoring the temperatures.

 

As you can see the CPU temperature is really high despite the low load. It fluctuates and even reaches 100C at some point. I heard that idle CPU temperature should generally be around 30C so this is pretty worrisome. The rest of the system components seem to be running in normal temperature. I searched up previous questions in this topic and people suggested cooler issue. But looking at cooler status the fan and pump are working properly. I followed the manual of H100i v2 and don't see any place I could've attached wrong (even un-mounted and re-mounted the heatsink just in case). I didn't change any configuration so it shouldn't be overclocked. I am going to buy a separate thermal paste and see if that helps, but in the meanwhile would like to see if people on this forum have seen this issue or know what could've been wrong. Thank you so much!

Thats really high.
Your H100i's temp meanwhile is just nice and i see that you're using the Extreme Fan setting for the pumps and fan.
Can you check if you mount the cooler properly?

Thanks for the response! I took the cooler off and re-mounted it and nothing seemed to have changed. There are just 4 parts: mounting screws, bracket, cooler, and standoff screws, and they all seem pretty straight forward to not be put on incorrectly...

 

Though when I took the cooler off I saw that the thermal paste seemed smudged:

Can this possibly affect cooler performance?

@Norine looks like from your pictures that you didn't have good mounting pressure to the one side where you see the pre applied thermal paste is not disturbed (as I've marked in red below), i.e. not smudged.  Try remounting the water block  again and for good measure you can also reapply new thermal paste.  Hope this helps and good luck.

Hmm... I think I might've figured out the problem. I also used HWInfo and Core Temp and the temperature readings seem much more normal:

 

And googling Corsair Link and Ryzen 2700x suggested that the software is not displaying CPU temperature for Ryzen 2's properly... I put my hand near the cooler and it didn't feel warm. I would believe this is a false alarm. Wasted a few days of time but I'm glad that this means the system is working properly. Thank you @Zirkov and @mikedrewsmy for the help
